Soil bacteria produce Vitamin B12 — which is essential for humans in order to protect neural health and reduce inflammation. But modern agriculture and other human behaviors decimate these bacterial colonies that produce B12.

We love nature and spending time outdoors. But we also wear clothing, and most of us work inside during daylight hours. That means our natural ability to soak up the sun's rays is limited, and as a result, many of us — regardless of dietary pattern — might be deficient in Vitamin D

Benefits: Protects from a host of chronic diseases, from osteoporosis to heart disease, some cancers, and even multiple sclerosis.

The Smart Part: While many vegan multivitamins contain the less effective D2 form, Complement Plus™ provides 2,000 IU of the only truly vegan D3 available (Vitashine, sourced from lichen) per daily serving.

Vegan food sources of Omega-3s like flax and chia seeds don't provide two essential types — namely DHA and EPA. Seeds provide ALA Omega-3's, and are an amazing addition to your plate, but most people do not convert ALA into DHA and EPA.

The Smart Part: Complement Plus™ includes 300 mg of DHA and 150mg of EPA per daily serving, sustainably sourced from algae grown under controlled conditions and tested for purity.

Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual and developmental disabilities. In plant foods, iodine is found inconsistently and depends on the iodine content of the soil. It's possible to get enough iodine if you regularly eat seaweed (multiple times a week), or use iodized salt, but this is one essential nutrient that shouldn't be overlooked whether you're vegan or not.

Benefits: Supports healthy thyroid function, which regulates the metabolism.

The Smart Part: Complement Plus™ includes 150mcg of Iodine per daily serving, sustainably sourced from kelp.

Our depleted soil may mean that plant foods, in general, do not contain enough Selenium (and that's even true for some Brazil nuts).

Benefits: Helps protect from neurodegenerative disorders like Alzheimer's and Parkinson's disease, mood changes, cardiovascular disease and cancer, as well as reproductive problems in men and women.

The Smart Part: Similar to Magnesium, Selenium works in tandem with Iodine to promote healthy thyroid function and metabolism, as well as the removal of heavy metals from the body. Complement Plus™ includes 50mcg of Selenium per daily serving, in the naturally occurring, plant-sourced form of L-selenomethionine.

K2 isn't available in plant-based foods except for natto, a Japanese fermented soy product (and it's not in tempeh), so those eating Western diets need to supplement in order to get it.

Benefits: Helps with blood clotting, reduces the risk of heart disease, prostate cancer and osteoporosis.
